Fault Symptom Codes
This section lists the Fault Symptom Codes that may be returned by
the REQUEST SENSE (03h) command. The Fault Symptom Code is
returned as byte 28 in the Extended Sense Bytes. It is an
Exabyte-unique byte that specifies the reason for the most recent
Check Condition status.
Note: You can also use the Fault Symptom Code field to determine
the location of errors in data sent with the MODE SELECT
(15h) command and the LOG SELECT (4Ch) command. For
more information about this use of the Fault Symptom Code,
refer to Section 10.17 for MODE SELECT and Section 8.5 for
LOG SELECT.
For ease of reference, the Fault Symptom Codes (FSC) are listed in
hexadecimal order. The information provided for each code includes
the sense key (SK) associated with the code, an error recovery
procedure (ERP) code, and a brief description of the problem or event.
Note: For more information about the suggested actions for each
ERP code, refer to “Error Recovery Procedures” on page E-16.
Important
The Fault Symptom Codes may change as new revisions of
the CTS firmware become available. For this reason, be sure
to check the documentation provided with new firmware
releases for the most current list of codes.
